Addison's disease is caused by low secretion of:
Correct answer: D. Melanophore stimulating hormone
- A. Cortisol hormone
- B. Adrenocorticotrophic hormone
- C. Luteinising hormone
- D. Melanophore stimulating hormone
Explanation
Addison's disease is primarily characterized by a deficiency in cortisol production. Cortisol is a critical steroid hormone that helps control metabolism, immune response, stress response, and inflammation. In Addison's disease, the adrenal glands do not produce enough cortisol, leading to symptoms such as fatigue, weight loss, low blood pressure, and hyperpigmentation.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
